Most of us could stand to drink more water—but there is too much of a good thing.

Dietitians constantly remind us that drinking enough water is absolutely vital in order for our bodies to function properly. And it is—unless you drink too much of it. Though most people look out for the signs of dehydration, overhydration is equally as dangerous. Drinking too much water can result in water intoxication, also known as hyponatremia, causing the inside of cells to flood due to abnormally low sodium levels in your bloodstream. In severe cases, water intoxication can lead to debilitating health problems such as seizures, coma, and even death.

You NEVER leave the house without a water bottle and constantly have one in hand

If you carry around your water bottle all day and immediately refill it when it depletes, you may be drinking too much water. Constantly adding water to your body can result in low sodium levels in your blood, which can cause all of the cells in your body to swell. According to Tamara Hew-Butler, DPM, PhD, an exercise science professor at Oakland University, this can become particularly dangerous when your brain starts to swell. “Your brain can only swell about 8 to 10 percent before it reaches the skull and it pushes your brain stem out,” Dr. Hew-Butler says.

You drink water even when you’re not thirsty

The best way to know if your body really needs more water is to be consciously aware of whether or not you actually feel thirsty. “Our bodies are so programmed to fight against dehydration because we’ve always been living in fear of scarcity or not having enough, so we have all of these built-in mechanisms to protect us against that,” Dr. Hew-Butler says. “One of these mechanisms that all animals have is thirst. Thirst is every body’s individual monitor that lets them know if they need more. The more water you need, the thirstier you get.” These are unexpected reasons you’re always thirsty and drink too much water.

You continuously drink water until your urine is clear

If you’re drinking a healthy amount of water, the color of your urine should be straw-colored to transparent yellow. Though most people believe clear urine is the healthiest sign of hydration, however, having urine with no pigmentation at all may be a sign that you’re drinking too much water. For most people, eight to ten glasses of water a day is considered a normal amount. This suggestion varies depending on an individual’s height, weight, and exercise patterns. Here’s what happens to your body when you drink the right amount of water.

You urinate frequently, including during the night

You may be drinking too much water if you find yourself often waking up in the middle of the night to use the bathroom. Most people urinate between six and eight times a day. If you find yourself urinating more than ten times a day, you may be drinking more water than your body needs. To prevent nighttime urination, have your last glass of water a couple hours before bed to give your kidneys time to filter the water through your body.

You feel nauseous and may experience vomiting

The symptoms of overhydration look a lot like those of dehydration, according to Hew Butler. When you drink too much water, your kidneys become unable to rid of the excess liquid and water starts to collect in the body. This can cause a number of unpleasant symptoms, often including nausea, vomiting, and diarrhea. But if you’re ever feeling stressed, this is why you need to drink water.

You have throbbing headaches throughout the day

Headaches are both a sign of overhydration and dehydration, similar to nausea, vomiting, and diarrhea. When you drink too much water, the salt concentration in your blood reduces, causing the cells in the organs throughout your body to swell. When your salt concentration is low, your cells grow. When you drink too much water, your brain actually grows in size and presses against the skull. This added pressure can cause a throbbing headache and more serious health problems such as brain impairment and trouble breathing.

You notice swelling or discoloration in your hands, lips, and feet

In many cases of hyponatremia, people will experience noticeable swelling or discoloration in their hands, lips, and feet. When all of the cells throughout your body swell, your skin will start to visibly swell as well. Those who drink too much water may gain weight suddenly, due to swelling and excess water in the bloodstream. If you’re drinking more than ten cups of water each day and notice swelling or discoloration in your hands, lips, and feet, consider cutting back on your water intake and see if your symptoms subside. Did you know there are actually benefits of drinking plain, hot water?

Your muscles feel weak and tend to cramp easily

Having a healthy, fully functioning body is all about balance. When you drink too much water, your electrolyte levels drop and that balance is compromised. Low electrolyte levels can cause a number of unpleasant symptoms, including muscle spasms and cramping. You can prevent muscle problems by replacing a couple glasses of water a day with coconut water, which is full of electrolytes and 100 percent natural.

You feel tired or fatigued

Your kidneys are responsible for filtering the water you drink through your body and making sure the fluid levels in your bloodstream stay balanced. When you drink too much water, your kidneys have to work even harder, creating a stressful reaction from your hormones that leaves your body stressed and fatigued. If you’re constantly drinking water and find yourself struggling to get out of bed, it may be because you’ve added unneeded stress to your kidneys. Next, learn how much water you should really be drinking every day.
